Antimony (Sb) and arsenic (As) are two hazardous metalloid elements, and the biogeochemical cycle of Sb and As can be better understood by studying plant rhizosphere microorganisms associated with Sb mine waste. In the current study, samples of three types of mine waste-Sb mine tailing, waste rocks, …

Plant-to-plant differences in Sb absorption. Antimony uptake varies widely among plant species, growing sites, and underlying substrate conditions (Table 1). Most commonly, the highest plant Sb concentrations occur in mining areas where the concentration of Sb in the soil is appreciably high (sometimes more than 1000 mg Sb kg …

2.2 Phytoremediation of Arsenic and Antimony in Mining Areas/Soil. Mining areas can be rehabilitated by plants with potential to accumulate metals and/or metalloids. Plant species spontaneously growing in mining areas contaminated with Sb and As naturally accumulate these metalloids, mainly when in an available form (Levresse et al. …

Environmental context. Soil contamination by antimony (Sb) has become an environmental problem of much concern in recent years, because increasing mining and industrial use has led to widespread soil contamination by this biologically unessential, but potentially carcinogenic element. We reviewed the available literature and found that Sb …

Abstract. Many crops cultivated in mining areas have been found to accumulate high levels of antimony (Sb) in their edible parts, thereby causing potential risks to human health. Understanding the behaviours of Sb in plants is important, particularly the mechanisms involved in its uptake, toxicity, detoxification and accumulation in crops.
